A hemisphere and a cylinder |
2008-05-18 |

From Libby:
A giant scoop, operated by a crane, is in the shape of a hemisphere of radius 24 inches. The scoop is filled with molten steel. The steel is then poured into a cylindrical storage tank with diameter 32 inches. How high will the molten steel rise?
I got the volume of the hemisphere and the volume of the cylinder, but I'm not exactly sure what to do next.
